Disubstituted alkylphenols most commonly employ two numerical locants to designate the positions of each alkyl group on the aromatic ring. Thus 2,6-bis (1-methylpropyl) phenol or l,6-6i-sec-butylphenol (2,6-DSBP) refer to the following disubstituted structure (Structure 3.2) ... 

Flotation Reagents. Only one sulfide mineral flotation collector is manufactured from phosphine, ie, the sodium salt of bis(2-methylpropyl)phosphinodithioic acid [13360-78-6]. It is available commercially from Cytec Industries Inc. as a 50% aqueous solution and is sold as AEROPHINE 3418A promoter. The compound is synthesized by reaction of 2-methyl-1-propene [115-11-7] with phosphine to form an iatermediate dialkylphosphine which is subsequently treated with elemental sulfur [7704-34-9] and sodium hydroxide [1310-73-2] to form the final product (14). The reactions described ia equations 10 and 11... 

Di-sec-butylphenol (DSBPJ is produced by the alkylation of phenol with 1-butene or 2-butene under acidic or aluminum catalysis. The production of di-j -butylphenol under acid catalysis gives a 2 to 1 mixture of 2,4-di-j -butylphenol and 2,6-di-j -butylphenol [2,4-bis(l-methylpropyl)phenol and...

Figure 12.11 shows the pyrograms of vinyl paints from two monochromes by the Italian artist Piero Manzoni. The two paints are clearly different in composition acetic acid (peak 1) and benzene (peak 2) are present as common markers of the PVAc binder in both cases, but sample (a) contains dibutyl phthalate (peak 6) as external plasticizer. Peak 5 was recognized as bis(2-methylpropyl)-phthalate which is formed from dibutylphthalate isomerization, while butyl acetate (peak 3) and butyl benzoate (peak 4) are secondary products of recombination reactions occurring during the pyrolysis. Sample (b), however,...

One example is the spectrum for the peak eluting at 44.83 min., which can be assigned to 2,4-bis(2-methylpropyl)-8-methyl-1-nonene, the trimer of 4-methyl-1-pentene. This spectrum is shown in Figure 6.1.28. 

Grower complaints of poor shattercane control with EPTC became numerous by 1977. Loss of efficacy was initially attributed to misapplication, inadequate incorporation, and adverse environmental conditions. However, the continuing widespread reports of unsatisfactory control with EPTC suggested other unknown factors must be involved. Field and greenhouse studies were initiated in 1978 to identify the reasons for poor field performance (1-3). Interestingly the problem appeared to be associated with repeated annual application. Though the extent of EPTC failure was unknown at the time, a 1983-8A survey revealed that 60% and 45% of corn growers in south central Nebraska who used butylate [S-ethyl bis(2-methylpropyl)carbamothioate] or EPTC were dissatisfied with their weed control (4). This was probably representative of the situation in 1978. 

The intramolecular cyclopropanation of several unsaturated diazo carbonyl compounds83 is most efficiently catalyzed by the Aratani complex (A)-4. Thus, 1-diazo-5-hexen-2-one is converted into (15",5i )-2-oxobicyclo[3.1.0]hexane with 77% ee, An interesting aspect of this study is the activation of the catalyst by bis(2-methylpropyl)aluminum hydride, which reduces the copper(II) to give a copper complex. Other unsaturated diazoketones with the / -complex 4 gave inferior results and with a-diazo /i-oxo esters, which require higher temperatures for carbenoid formation, the enantiomeric excesses were close to zero.
